Abstract (en)

[origin: EP3862165A1] To provide a biaxially oriented polyamide film, even as a product that is close to an end of a mill roll, having favorable mechanical characteristics, thermal characteristics, and few S-shape curling due to moisture absorption after being made into a bag. A biaxially oriented polyamide film formed of a polyamide resin containing not lower than 60% by mass of polyamide 6, wherein a molecular orientation angle of the film is not smaller than 20°, a strain at moisture absorption of the film is not higher than 1.3%, an impact strength of the film is not lower than 0.8 J/15 µm, and a heat shrinkage rate, after heating for ten minutes at 160°C, of the film is 0.6 to 3.0% in both an MD direction and a TD direction.
